Abstract

A method includes obtaining an active device layer. The active device layer has a first surface with one or more active feature areas. First portions of the active feature areas are exposed, and second portions of the active feature areas are covered by an insulating layer. A conformal overcoat layer is formed on the first surface. A base of a microelectromechanical systems (MEMS) device layer is formed on the conformal overcoat layer. The MEMS device layer is spatially segregated from the active feature areas by removing portions of the base of the MEMS device layer in one or more antiparasitic regions (APRs) that correspond to the active feature areas. Metal MEMS features are formed on the base of the MEMS device layer. Selected portions of the active feature areas are exposed removing portions of the conformal overcoat layer that overlay the active feature areas.
